31. The expert from OICA recalled the discussion at the previous GRSG session on ECE/TRANS/WP.29/GRSG/2015/36 proposing to amend the provisions of UN Regulation No. 67 to allow the installation of autonomous CNG heaters for the heating of the engine. The expert from Germany presented GRSG-110-27 further clarifying the text of paragraph 18.5.1.3.

32. GRSG adopted the proposal as reproduced below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as draft Supplement 5 to the 01 series of amendments to UN Regulation No. 110.

Paragraph 18.5.1.3., amend to read:
“18.5.1.3. Notwithstanding the provisions of paragraph 18.5.1.2.
(a) the automatic cylinder valve may stay in an open position during commanded stop phases, and
(b) in the case where a fire alarm system is installed in the compartment where a CNG combustion heater is located, the automatic cylinder valve(s) may be opened by an electronic control unit for the purpose of permitting its operation to warm the engine coolant.”

35. The expert from the Netherlands introduced GRSG-110-26 (superseding ECE/TRANS/WP.29/GRSG/2016/8) proposing an amendment to UN Regulation No. 110 to allow Class 0 hoses with couplings using sealing technologies other than those with a 45° cone and, thus, to avoid design restrictive requirements. The proposal received a number of comments.

36. GRSG adopted the proposal as reproduced below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as part (see para. 32 above) of draft Supplement 5 to the 01 series of amendments to UN Regulation No. 110.

Annex 4B, paragraph 1.6.2.2., amend to read:

“1.6.2.2. The interface type for the hose coupling shall be:

(a) sealing cone of swivel-nut type of the type with a half vertical angle of 45°, or
(b) other couplings complying with the tests described in paragraph 1.7., as well as the tests mentioned in Annexes 5A and 5B.

Couplings shall have complementary counterparts."

37. The expert from the Netherlands presented ECE/TRANS/WP.29/GRSG/2016/9 aimed at correcting a typographical error and clarifying the current provisions of the Regulation. He also introduced ECE/TRANS/WP.29/GRSG/2016/10 proposing to insert provisions for LNG fuel connector as specified in ISO 12617:2015. Both documents received a number of comments. The expert from France raised a study reservation on the reference to the ISO standard in paragraph 2.2. of Annex 4J. Following the discussion, GRSG adopted both proposal as reproduced below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as part (see paras. 32 and 36 above) of draft Supplement 5 to the 01 series of amendments to UN Regulation No. 110:

Paragraph 7.1., correct “paragraphs 8.12. to 8.21.” to read “paragraphs 8.12. to 8.22.”.

Annex 4A, paragraph 4.2.4., correct “of Class 1 and Class 2” to read “of Class 2”.

Annex 4H, paragraph 2.2., correct “than 5 seconds” to read “than 2 seconds”.

Annex 4J
Paragraph 2.2., shall be deleted.

Paragraph 3.1.6., correct “shall be not be” to read “shall not be”.

Insert new paragraphs 4. and 4.1., to read:
“4. LNG filling receptacle dimensions
4.1. Figure 1 shows the dimensions of the LNG filling receptacle.

Figure 1

"

38. GRSG agreed to resume consideration at the next session of GRSG on the ISO reference on the basis of a revised proposal jointly prepared by the Netherlands and NGV Global, taking into account the comments received.

35. The expert from OICA shortly introduced ECE/TRANS/WP.29/GRSG/2015/36 on autonomous CNG heaters for the heating of the engines, but he preferred to have a detailed consideration of the proposal at the next session of GRSG. GRSG endorsed that suggestion.
